What did you get as your possible values? I'm struggling to see what the problem might be.

x= -12 and 8 so since the inequality is less than 0 and it's an upwards curve, the possible values will be -12<x<8

i listed all the values between -12<x<8 which was my answer for c), the mark scheme said something different

A distance can't be negative.
from pt a) x>5.5
and x needs to be between -12<x<8
So what values can x be?
